Lunati Voodoo Cam Opinions... Looking at this cam to put in my 02 SS....
What is everyone's opinion of this particular cam?
I want something with a nice lope (Not extreme), good HP gain, and very streetable.
I'm going with PRC dual valvesprings, hardened pushrods, and pacesetter headers & y-pipe with this....
SPEC SHEET ON CAM
222/228 .567 Lift 113/109 LSA ICL (Has 4 degrees of timing built into cam if set to TDC)

No need for dual springs. Stick to Comp 918's for that one.

It has -1* overlap @ .050". For ex my TR224 112LSA has 0* overlap. It will have a nice short chop to it. It should produce a nice broad power curve and give an easy 40rwhp gain over the stock cam.
On a stock LS1 longblock w pistons .0007 out of the hole and 0.052 head gasket your DCR will be around 8.01-1.

Sorry to ask, but what do you mean?
With a 4.11 gear and flowmasters, tuned, my car dynoed at 327rwhp and 350ft/tq....
At the time of the tune, my Air to Fuel ratio was DEAD ON, BEFORE the tune. My tuner (pcmforless.com) was able to add timing to gain HP.
I'm currently running a stock 3.42 gear now...
I'm replacing the #7 piston as we speak b/c spark knock (my stupidity by running 87 octane on a 93 octane tune)...
Check out TDC where SPARK KNOCK pulled a chunk out the the # 7 piston....
LOL
Anyways, I'm replacing the bad piston with a OEM piston.
I'm guessing that I should have the head decked and pressure tested?

It's actually running a 109 LSA with 4 degrees built into the camshaft at TDC, right?
If I set the timing on the chain -4 degrees off (109 LSA?), would I get a better lope by having my tuner tune it based on the timing chain set at TDC or by having it set at TDC, (113 LSA)?
Am I reading this right?
Bottom line, I'm new at this.... How would YOU set it up, since it has 4 degrees of timing ground into the camshaft?

I have that cam in my car-it does have a bit of a chop which surprised me-it makes power everywhere. It made 645 rhwp 541 rwtq with 11 psi from a D1SC-probably would of made more but we only pulled it to 6400-the curve was still going up!

That will give you your overlap in degrees

I have a few programs that I can run cam specs on and get feedback. PM me with your email and I can send one to ya.
LSA or Lobe Seperation Angle is ground into the cam and does not change unless the cam is reground. Advancing or Retarding the cam will change the ICL or intake Centerline. In a nutshell advancing results in broader lowend and mid power where retarding will broaden the upstairs power curve.
If it were mine I would install it 113 109ICL as it comes from Lunati. Retarding the cam will only lower your DCR or Dynamic Compression Ratio.
From what I've been told, TDC on the cam will add 4 degrees of timing, eliminating the need for an INITIAL tune to keep it running (I'd actually have it dyno-tuned for optimum results).

This is actually the first time I have seen the equation in the form you posted....will have to remember it

WOW. I love this site!
So overall, it looks like that's a great cam for a stock bottom end bolt on car...
I'm feeling even better about my choice!
